Background:
I'm a mechatronics student that is into cosplaying and had an idea to implement electronics with my cosplay. (not an new idea)
I want to make a cosplay of Viktor from the Game League of legends. Viktor is cyborg scientist and has a 3rd robotic on his left shoulder. His robotic arm has 5axis. The last axis has a hand with 4 fingers. he has a emote where His robotic arm grips his staff/kayn and hold it in the air. Planning of designing it as light as possible. I'm going to control the light in the staff with arduino as well.(that's an other project)
I have solidworks and eplan to design. I can 3d print at friend or school. have looked online for possible robotic arm build but the usually don't give me enough information about
This project might be a little hard without a lot of experience. But i don't have a convention planned yet. So there is no real deadline.
My plans:
I want to make a portable robotic arm from scratch. With a payload of around 1kg (depend on the weight of the staff). it's reach between 550mm and 720mm. My own arm is around 660mm
it has to be light weight because i will be carrying this thing on my shoulder for atleast 4hours. i think about MAX 5KG
I want it work at least 3hours up to 8 hours on accu/batterie.
I want to make idle animations but if there is a huge crowd i need to tell it not move.
I want to so i can controller the arms with a PS/XBOX controller or a IR remote.
Probably need a safety switch near my belt for when something goes wrong.
The gripper should have between 2 and 4 fingers or a humanoid hand that can grib the staff.
Some Insane idea's:
Upgrading it to hand motion controlled or Mind controlled.
Implementing vision or pressure sensors so the arm knows when a object is near it.
( i will learn about vision at next month internship)
Having some kind of input to control the arm with my staff as well.
Making is operational for for 8+ hours.
Making arm armour with an interface that spits out data like Voltage,ampere, power used and batterie charges
Questions:
Some question to people with robotic arms:
How much does it weight?
On What voltages do the motors run?
What motors do you use and why?
How much payload/reach does your arm have?
How much power does your arm use?
Has anyone made a portable robotic arm before?
Although i need to do more research myself, learn more about arduino and Start designing the arm.
Maybe i should start with the staff first so i can properly design the arms payload around it. i appreciate all help and tips. tell me all about it.
Thanks for reading
